Magnet system

Large openness structure

OPENMARK 5000 adopts the rear asymmetrical dual-pillar design, under the premise of ensuring the stability of the structure, the canning space is maximized, the front opening angle can reach 280°, which will offer a maximum comfort for patients, especially for obese patients, claustrophobic patients, and children.

Unique shimming technology

Homogeneity of the main magnetic field is the basis of MR imaging. A good magnetic field homogeneity helps to realize a wide range of abdominal scanning and off-center joints scanning.

ANKE provides unique shimming technology, which is combined with passive and active shimming during scanning. This can greatly improve the image quality of large FOV scanning and off-center scanning, you can easily to achieve high-quality imaging of whole body.

Intelligent temperature control system

Permanent magnet is very sensitive to temperature draft. OPENMARK 5000 is equipped with a intelligent temperature control system, to keep the magnet in a constant temperature, which will ensure a high stability of magnetic field.
